ghetdjc320 Posted October 25, 2020 Share Posted October 25, 2020 I think a YJ axle *may* also bolt right in. Link to comment Share on other sites More sharing options...

I remember a topic about swapping an mj 44 into a YJ. It’s been several years back but iirc it was a bolt in. Link to comment Share on other sites More sharing options...
Pete M Posted October 26, 2020 Share Posted October 26, 2020 getting new perches welded on to an XJ axle is an easy task. Link to comment Share on other sites More sharing options...
MiNi Beast Posted October 26, 2020 Share Posted October 26, 2020 are you talking axle swap so don't have to replace gear gear? you can replace the internal gears with any d35 from xj. will have to double check backlash but slap it together and run it. you can replace just the spider gears as well if thats the issue with out replacing the whole axle or carrier. but if want a bolt in axle consider the corp 14 bolt, as it bolts right in as a soa conversion. but that's 8 lug 1 ton stuff. but bolt in upgrade for about $150.

Showgoer Posted November 10, 2020 Author Share Posted November 10, 2020 Ok gents Iv changed the whole rear . Now Iv got a bad vibration. Changed u joints as well. I’m thinking piñon angle is off. How do I correct the piñon angle . ?Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Big_Mark Posted November 10, 2020 Share Posted November 10, 2020 Has your driveline angle or length changed? Is the pinion in the new axle loose? Those are the likely suspects for vibrations Link to comment Share on other sites More sharing options...

MiNi Beast Posted November 10, 2020 Share Posted November 10, 2020 may need shims under the leafs to correct angle. angle finder is your friend here. and with the new leafs, are they in properly. front to back that is? Link to comment Share on other sites More sharing options...
omega_rugal Posted November 10, 2020 Share Posted November 10, 2020 does that vibration is there all the time and becomes worse as you accelerate? if yes then is the angle... Link to comment Share on other sites More sharing options...
BeatCJ Posted November 10, 2020 Share Posted November 10, 2020 Swapping a Comanche axles into a Comanche should give you about the right pinion angle. I would look elsewhere. Something you changed? Link to comment Share on other sites More sharing options...
